You can choose from a range of options when planning your trip: the festival in May, shorter walks to viewpoints, a longer hike, or cultural and historical discoveries.

Peiron Tradition on Aioi Bay

The Aioi Peiron Festival is held every May in Aioi Bay, in the municipality of Aioi. The festival program includes a race featuring four Peiron boats, a fireworks display over the water on the eve of the festival, and a land parade. The exact dates and program vary from year to year; if you want to plan your trip around the festival, check the latest announcement.

The history of the race in the municipality of Aioi dates back to 1922, when employees of the Harima Shipyard who came from Nagasaki brought the Peiron race to the municipality. The festival in Aioi thus combines a water race with a local tradition and a land parade. The festival events that interest you most can help shape the focus of your stay.

At Manyō no Misaki in the municipality of Aioi, a camellia garden is home to around 30 varieties and more than 200 trees. From December to April, red, white, and pink camellias bloom in succession in the garden. The flowering season there depends on the year and the weather.

Mitsuyama is the highest mountain in the municipality of Aioi; the hike is listed as taking about four hours.

From the park, the view extends across the southern urban area of the municipality of Aioi and Aioi Bay.

You can also discover local plant life at specific sites. In the municipality of Aioi, Koyasunoki grows alongside Chitosekazura in evergreen broadleaf forests along valleys, including near Iwaza Shrine and in Uryu Rakankei.

Castle Ruins and Local History

The Kanjōzan Castle ruins in the municipality of Aioi are located on 301-meter-high Kanjōzan, which extends across Yanocho Uryu and Mori. The ruins include stone walls, building remains, foundation stones, and the remains of wells. The Kanjōzan Castle complex is considered an important medieval mountain castle in the Harima region. Rakan no Sato in the municipality of Aioi is a park with a campground, recreation area, children’s forest, and the Kanjōzan Castle ruins.

A local tradition in the municipality of Aioi concerns Yano no Ōmuku, which is said to be more than 600 years old. According to the tradition, Yano no Ōmuku was revered and protected as a sacred tree at the site of a former grove belonging to Kōjin Shrine. Its claimed age is therefore explicitly a matter of tradition, not a verified age.

Choose a Vacation Rental to Suit Your Itinerary

When looking for a vacation rental in Aioi, your preferred focus for the trip can be a useful first filter: if the Peiron Festival in the municipality of Aioi is your main interest, plan around the dates in May, which vary from year to year. For other interests, you could compare the roughly four-hour hike at Mitsuyama with the approximately 15-minute walk to the viewpoint near Tomiyama Park, or take the seasonal camellia bloom at the garden on Manyō no Misaki into account.
